bicolormap(gap=0.1, mingreen=0.2, redbluemix=0.5, epsilon=0.01, demo=False, apply=False)[source]#

This function generators a two-color map, blue for negative, red for positive changes, with grey in the middle. The input argument is how much of a color gap there is between the red scale and the blue one.

Parameters:

gap (float) – sets how big of a gap between red and blue color scales there is (0=no gap; 1=pure red and pure blue)
mingreen (float) – how much green to include at the extremes of the red-blue color scale
redbluemix (float) – how much red to mix with the blue and vice versa at the extremes of the scale
epsilon (float) – what fraction of the colormap to make gray in the middle
demo (bool) – whether to plot a demo bicolormap or not
apply (bool) – whether to apply this colormap to the current figure

Examples:

sc.bicolormap(gap=0, mingreen=0, redbluemix=1, epsilon=0) # From pure red to pure blue with white in the middle
sc.bicolormap(gap=0, mingreen=0, redbluemix=0, epsilon=0.1) # Red -> yellow -> gray -> turquoise -> blue
sc.bicolormap(gap=0.3, mingreen=0.2, redbluemix=0, epsilon=0.01) # Red and blue with a sharp distinction between
